Project information

The Princes Highway is an important urban arterial road, and forms part of the A1 road corridor. The A1 connects the south coast of NSW and Wollongong to Sydney. It also provides access to major roads including the M5 Motorway, A3 King Georges Road, A36 Princes Highway (city) and M1 Pacific Highway.

Road users are currently experiencing congestion due to high volumes of vehicles travelling along the corridor and turning right at the intersections of Acacia Road, Oak Road and Kingsway. In addition, there are currently high volumes of vehicles travelling in both directions on President Avenue and the Princes Highway. These delays are caused by turning vehicles blocking through traffic.

This project aims to ease congestion at these intersections and improve journey reliability for all road users.

Benefits include:

  • improved operation of Princes Highway along the corridor and at the intersections with Acacia Road, Oak Road, Kingsway and President Avenue
  • improved safety at the intersections, with a reduction in the number of rear-end crashes and crashes involving motorists changing lanes
  • reduced traffic delays and a better flow of traffic for motorists at all points along the corridor.

Since work started in April 2018 we have:

  • started work to upgrade the central median on Princes Highway
  • moved services and relocated utilities on Princes Highway and President Avenue
  • moved the median strip, relocated the traffic lights and extended turning lanes at the intersection of

President Avenue and Acacia Road.

  • extended the northbound right-turn slip lane on Acacia Road approaching President Avenue
  • completed a new left-turn slip lane from Princes Highway onto Kingsway
  • constructed a new retaining wall on the northern side of Princes Highway between Acacia and Oak roads, and carried out utility upgrades
  • completed early works eastbound on the northern side of Princes Highway to prepare for new lanes.
  • Night works will continue on Princes Highway
  • Completion of the retaining walls on Princes Highway
  • Construction of a new southbound left-turn lane from Oak Road onto Princes Highway
  • A third eastbound right-turn lane will be constructed from Princes Highway into Kingsway
  • Continuation of drainage on the Princes Highway.

Roads and Maritime invited feedback on the proposal in May and June.2017. A total of 220 submissions were received in response to the display of the Review of Environmental Factors (REF). This included one submission from the Sutherland Shire Council, and 219 submissions from the community. Of the total submissions, 19 were in support of the proposal, two opposed the proposal, 142 did not state a preference on the proposal, and 56 were not relevant to this proposal (i.e. concerned other proposals of the Gateway to the South Pinch Point Program, or more general road network improvements).
